I Specification of Letters Patent.

Application filed November 18, 1908. Serial No. 463,146.

To all whom t may concern:

Be it known that I, ROBERT M. DIXON, a citizen of the United States, residing at East Orange, in the county'of Essex and State of New Jersey, have invented certain new and useful Improvements in Hot-Water Systems, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a system for heating water, and more articularly for heating toilet water for rai road cars.

One of the objects thereof is to provjide a system of this character in which fthe water may be kept warm for some time after the car has been detachedfrom the original heatsupplying means.

Another object of theinvention is to provide means in a system of this type, whereby the water will be prevented from freezing.

Another object is to provide apparatus of the above nature which will be simple in construction and cheap to manufacture, and which will be eli'cient and reliable in opera.- tion.

Other objects will be in part obvious and in part pointed out hereinafter.

The invention accordingly consists in the features o f construction,` combinations of elements and arrangementsof parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims. 1

In the accompanying drawings, wherein is shown Aone of various possible embodiments of the invention, Figure l isa perspective View showing various parts of the system in position with relation to the car; Fig. 2 is an enlarged detailed View of the Water receptacle and the parts adjacent thereto; Fig. 3 is a longitudinaly section through heating jackets showing the manner of heating the Water; FiO. 4 is a. vertical section of a fitting; and Flg. 5- is an end view of a Water tank showing the connections thereto.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring to the drawings, l indicates the floor of the car to the under side of which a tank or receptacle 2, adapted to contain water,

is secured in any suit-able Ina-nner. The Water is drawn from thevbottom. of the tank by means of the pipe 3 which passes out at the top of the tank to a= T or other suitableooupling 4 at which point the iiow of the water is divided, the cold water passing through the piping 5 to the pipes 6 and 7 through which it is led to the toilets at the ends of the car. The water for the hot water supply passes from the T 4 to the pipe 8 which communicates with a passage 9 formed in the lower portion of the fitting 10, which may be termed the director fitting, said passage being preferably curved as shown to direct the water into the pipe 11 which is surroundedib a suitable casing or jacket 12 secured within the heads 13 and 14, as clearly shown in Fig. 3. The water then passes through the pipe 15 which is preferably supported Within the heads 14 and 16 ajnd surrounded by a jacket 17, the crossse'ction of which is preferably smaller than the cross-section of the jacket12. lpon leaving the pipe 15 the water is then led through the piping 18 to the toilet at one end of the car, then by the piping 19 to the toilet at the opposite end of the car, from which it returns through the piping 20 to chamber 21.

`23 leading to the interior ofthe jacket 17 through the passage 24: formed in the head.

16, the steam bein thus caused to pass into and through said jacket and in contact with the Water pipe 15. After passing through this jacket the steam is then led through a suitable passage 25 formed in the head 14 to a pipe 26 which extends throu h the larger of the jackets and is conneotedg to a pipe 27 which communicates with a suitable steam trap 28. i It will thus be understood that when the main train pipe 22 is connected to a suitable supply of steam the water Within the pipes 11 and 15 will be kept hot and the property ready for use. In order to insure the water being kept warm for some time after the supply of steam has been cut off there is placed within the jacket l2 and preferably surrounding the water pipe 1l and `steam pipe 26 a suitable substance 29 which has of rapidly absorbing and retaining heat. In practice it has been found that calcium chlorid possesses this property to a high degree, as such'substance crystallizes` at a temperature of about 82 degrees, and when heated above this temperature becomes a liquid and absorbs heat rapidly, thereby storing after the steam has been cut 0E, will be im- Y parted to thewater within the pipe 11 until the temperature of the substance again falls to about 82 degrees, at which point it again assumes its crystallized form. In order to prevent the heated water from being forced back into the tank on account of its expansion, the diameter of the ipe 8 which leads from the tank 2 to the director fitting l0 is greater than the diameter of the pipe 11, being preferably of about twice that of the latter pipe. The increased area of the pipe 8 will, therefore, permit any expansion of the Water to be taken up before it reaches the T 4:. Y

In arranging the piping throughout the car the piping through which the cold Water iows is preferably placed as shown in `close proximity to the hot Water pipes, by means of which the water in said cold Water pipes is kept from freezing.

It will be seen from the above description that I have provided a system by means of which the water supplied to the toilets in l cars may be heated and at the same time heat may be stored up to lmaintain said water in heated condition after the steam supply has been disconnected.

lAs many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative` and not in a limiting sense.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

l. In a system of the class described, in combination, a system of piping through which a Huid -is adapted to circulate, a

heater operatively associated withsaid pip.

up a quantity of heat which,

ing, a conduit connectedto a source of supply of a heated medium and to said heater for conveying said mediumto said heater whereby the fluid circulating 'through said piping will be heated7 a jacket surrounding said piping, heat storing material contained therein, and means communicating with said heater for conveying the heating medium therefrom into operative' relation kto said storing material.

2. In a system of the class described, in combination, a system of piping through which a fluid is adapted to circulate, a jacket surrounding said pipin and ada ted to be connected to a source o? supply o a heated medium, whereby the fluid circulating in said piping will be heated, a second jacket surrounding said piping, heat storing material contained therein, and a means com municating with said first jacket for conveying the heated medium therefrom into operativerelation to the material in said second jacket.

` 3. In a system of the class described, in combination, a system of piping through which a fluid is adapted to circulate, a jacket surrounding said piping and adapted to be connected to a source of supply of a heated medium, 'whereby the fluid circulating in said piping will be heated, a secondjacket surrounding said piping, heat storing means contained therein, and a pipe positioned within said second jacket and communicating with said first jacket for conveying the heated medium from said first jacket into operative relation to said heat storing material.

4. In a system of the class described, in combination, a system of piping through which a fluid is adapted to circulate, means adapted to be connected to a source of supply of a heated medium for conveying the 'said medium into close relation to said piping to heatthe fluid vcirculating therein, means comprising heat storage material surrounding a section of said pipe in advance of saidfirst means, and means inconductive relation to said storage material .through which the heated medium travels after its passage through said first means whereby the storage material will be heated by the residual heat of said heated medium.

In testimony whereof I afiix my signature, in the presence of two Witnesses.
